Several substituted quinolin-4-amines and heteroaromatic analogs were synthesized and evaluated for interaction with triplex polydA.2polydT and duplex polydA.polydT by using UV-thermal melting experiments. Excellent triple-helix DNA ligands with high affinity toward T.A.T triplets and triple/duplex selectivity were designed through a rational approach.
合成了几种取代的
喹啉-4-胺和杂芳族类似物,并通过紫外-热熔融实验评估了其与三链体polydA.2polydT和双链体polydA.polydT的相互作用。通过合理的方法设计了对TAT三联体具有高亲和力和三重/双重选择性的优秀三重螺旋DNA
